RESET
RESET
RESET - restore the value of a run-time parameter to the default value
Synopsis
RESET configuration_parameter
RESET ALL
Description
RESET
restores run-time parameters to their
default values.
RESET
is an alternative
spelling for
SET configuration_parameter TO DEFAULT
Refer to SET for details.
The default value is defined as the value that the parameter would
have had, if no
SET
had ever been issued for it in the
current session. The actual source of this value might be a
compiled-in default, the configuration file, command-line options,
or per-database or per-user default settings. This is subtly different
from defining it as
"
the value that the parameter had at session
start
"
, because if the value came from the configuration file, it
will be reset to whatever is specified by the configuration file now.
See
Chapter 20
for details.
The transactional behavior of
RESET
is the same as
SET
: its effects will be undone by transaction rollback.
